project 4: lighting engines

11/5/19 research + explorations

Types of Lights:

Types of Lighting:

(all above) lights seen at the Pittsburgh Vintage Mixer Fair

Things to Consider:

11/13/19 drafting models:

Draft 1:

(left) sketch of first idea; (right) a tab idea to hold the form
(above) trying out the tab method to hold the cylindrical shape
(left) side view; (right) failed attempt at lining the bottom with tracing paper

Draft 2:

(left) front view; (right) side view

Draft 3:

(left) idea sketch; (middle+right) bristol template for easy replication of the triangular prism net
(left) I used a ruler to help make precise creases when folding the prism nets; (right) the triangular prisms
(left) side view; (right) for the center base, I had pasted half half of tracing paper and printer paper to see how bright the light would shine through them.
(above) what the light looks like hung up

11/18/19 creating alternatives:

(above) other types of light I encountered at Home Depot
(above) new bulb!

Draft 4:

(left) brainstorming different ways to approach the ‘pattern’ repetitive design; (middle) initial sketch of draft; (right) ancient Chinese coins
(left) Yupo paper; (right) seeing how Yupo creases vs taping strips together
(left) layering clearprint Vellum to Yupo, layering swatch; (right) layers under light
(above) process of making one of four panels for exterior structure
(above) front and back of panel
(left) exterior shell; (right) second layer
(left) cut panels; (right) all three layers done
(left) example of paper curling after attempting to use UHU glue sticks; (right) used double sided and scotch tape to build the whole draft
(left) side view; (right) under view
(above) group critique exercise from class

11/20/19 creating variations:

(left) different ways to layer; (middle+right) draft brainstorming/plans
(left) Bristol on printer paper; (right) printer paper on Bristol
(left) printer on printer paper; (right) Bristol on Bristol
(left) sturdier Bristol; (middle) flimsy printer paper; (right) how the layers were taped on each panel
(above) joining panels together
(above) how I attached each layer to each other with Scotch tape.
(left + middle) placing all three parts and taping done; (right) adding clearprint Vellum to paper to hide the lightbulb

11/24–11/25/19 fine-tuning:

(above) creating the layers for exterior
(above) to prevent underestimating how long each panel is, I made each layer longer so that I could cut the excess off.
(left) cutting out windows from the Bristol; (right) taping clearprint Vellum
(left) Bristol layered on front and back; (right) What it looks like with light
(above) foam core fitted to the structure
(left) foam core fitted to inner square; (right) foam core fitted to second layer/square
